[texts]Observations of TeV gamma ray flares from Markarian 501 with the Telescope Array Prototype - Telescope Array Collaboration
We will report the observations of TeV gamma ray flares from Markarian 501 using Telescope Array Prototype. The observation were carried out continuously from the end of March to the end of July in 1997. The energy spectrum, and the time variation of the gamma ray intensities are shown. The intensity has been changed by the order of magnitude in this period and the possible quasi periodic oscillation of 12.7days were discovered.
[software]Array - http://www.mediumk.com/array/macosx
This program lets you create screens that look like the old Lite Brite game, with colored pegs that poke through a back-lit screen. Use the various functions to manipulate your design; then save and reload the animation. You can export your creations as Flash or QuickTime files. The documentation contains detailed instructions about using the program.

[software]Array-util - http://starbreeze.knoware.nl/~hugo/array-util/
Array-util is a small tool designed to collect information from a SmartArray controller. The program gives you an overview of all logical and physical drives, including basic information on sizes. Array-util is supposed to become a configuration tool in the future.

[texts]Highlights from Telescope Array - Yoshiki Tsunesada
The results from the first three years observation in Telescope Array are reviewed. The energy spectrum, mass composition, and anisotropy in arrival directions of ultra-high energy cosmic rays are discussed. The energy spectrum of cosmic rays with energies above $10^{18}$ eV is determined using the data of the fluorescence detectors, surface detectors, and with a hybrid shower reconstruction technique using the both data...

[texts]Periodicity in the TeV gamma rays and X rays from Markarian 501 - The Utah Seven Telescope Array collaboration
Historical TeV gamma-ray flares from Markarian 501 was observed using Utah Seven Telescope Array (7TA) from the end of March to the end of July of 1997. The Rossi X-ray Timing Explorer All Sky Monitor (RXTE ASM) has been observing X rays from Mrk 501 since Jan. 5, 1996. We find evidence for periodicities of $23.9^{+2.3}_{-2.0}$ days and $23.9^{+1.6}_{-2.9}$ days from TeV gamma-ray and X-ray light curves using 7TA and RXTE ASM...

[texts]TeV gamma-ray observations from nearby AGNs by Utah Seven Telescope Array - The Utah Seven Telescope Array collaboration
We have investigated TeV gamma-ray emissions from nearby X-ray selected BL Lac objects using the Utah Seven Telescope Array for more than two years. These objects can be considered as potential sources of TeV gamma rays with inverse compton model. The gamma-ray flares from Mrk421 and Mrk501 found in these observation will be reported.

[texts]The energy spectrum of high energy gamma rays from Mrk501 by the stereoscopic analysis - The Utah Seven Telescope Array collaboration
We have developed the energy measurement method which based on stereoscopic observation with multiple telescopes for TeV gamma rays. Energy resolution obtained by this method was 23 %. The energy spectrum of the gamma-ray flares of Markarian 501 in 1997 was also obtained using this techniques. We have confirmed the bending or the cutoff of the energy spectrum around several TeV.

[texts]A search for Extragalactic Sources of Ultrahigh-Energy Cosmic Rays - A. A. Ivanov
Possible extragalactic sources of cosmic rays at energies above 4*10^{19} eV detected with the Yakutsk array are sought. Correlation of the shower arrival directions with objects from Veron's catalog that are located closer than 100 Mpc from the Earth confirms the observations at the Pierre Auger observatory, as well as the Greisen-Zatsepin-Kuzmin effect on ultrahigh-energy cosmic rays. The detailed analysis of the data reveals the classes of objects belonging to the active galactic nuclei that ...
[texts]The Ultra-High Energy Cosmic Ray Spectrum Measured by the Telescope Array's Middle Drum Detector - Douglas Rodriguez
The Telescope Array's Middle Drum fluorescence detector was constructed using refurbished telescopes from the High Resolution Fly's Eye (HiRes) experiment. As such, there is a direct comparison between these two experiments' fluorescence energy spectra. An energy spectrum has been calculated based on one year of collected data by the Middle Drum site of Telescope Array and agrees well with the HiRes monocular spectra...

[texts]Cosmic Ray in the Northern Hemisphere: Results from the Telescope Array Experiment - Charles C. H. Jui
The Telescope Array (TA) is the largest ultrahigh energy (UHE) cosmic ray observatory in the northern hemisphere TA is a hybrid experiment with a unique combination of fluorescence detectors and a stand-alone surface array of scintillation counters. We will present the spectrum measured by the surface array alone, along with those measured by the fluorescence detectors in monocular, hybrid, and stereo mode...

McNamara (University of Waterloo) *Very Large Array Telescope Image Credit:* NRAO, and L. Birzan and team (Ohio University)
*Description*: This is a composite image of galaxy cluster MS0735.6+7421, located about 2.6 billion light-years away in the constellation Camelopardalis. The image represents three views of the region that astronomers have combined into one photograph. The optical view of the galaxy cluster, taken by the Hubble Space Telescope's Advanced Camera for Surveys in February 2006, shows dozens of galaxies bound together by gravity...
